ABSTRACT:
A slide type cap closure is disclosed comprising a cylindrically shaped closure member and a slidably interfitting disk member. The closure member forms a seal about the opening of the container on which it is mounted and includes an orifice extending upward from a recess formed along the top surface of the member. The recess has a pair of grooves extending along its length into which downwardly depending rails of the disk member slidably interfit. The disk member is dimensioned so as to move in a snap action manner along the upper surface of the closure member between open and closed positions. The disk member does not extend beyond the periphery of the closure member. The disk member in combination with the slightly protruding upper termination of the orifice forming member forms an extremely tight seal with the orifice when in the closed position.
